-LRB- CNN -RRB- -- Friends and family of Holly Bobo , last seen in 2011 , waited three years for news . Their worst fears have now been confirmed .

A man has been indicted on charges of kidnapping and murder in the case of the Tennessee woman , authorities announced Wednesday .

Zachary Adams , 29 , is being held without bond .

A Decatur County grand jury handed down a two-count indictment of especially aggravated kidnapping and first-degree murder .

`` As this investigation continues , we are still asking for the public 's help and support to help us continue to seek out justice regarding the disappearance of Holly Bobo , '' Mark Gwyn , director of the Tennessee Bureau of Investigation , told reporters .

Because the investigation is ongoing , Gwyn declined to comment on whether any human remains have been found .

Bobo , a nursing student , was last seen in April 2011 . She was 20 years old .

Her brother told authorities he saw a man in camouflage leading her away from their home in the small town of Darden .

The Bobo case rocked the largely rural swath of central Tennessee , from those who knew the young woman to others who rallied behind the effort to find her .

Hundreds of volunteers -- some on horseback and foot , others on all-terrain vehicles -- turned out to hunt for clues in Decatur , Henderson , Henry , Carroll and Benton counties . Many more attended memorial services or offered supportive thoughts online via groups on Facebook .

The TBI and local and federal authorities have spent hundreds of manpower hours on the case , Gwyn said . More than $ 450,000 has been offered in reward money .

Adams , who is being held at the Chester County jail , is set to appear in court on Tuesday . Prosecutors are evaluating whether they will seek the death penalty .

`` Obviously , they 're devastated , '' Gwyn said of the Bobo family .

`` They 've been devastated for three years . But , hopefully , this is the beginning of closure for the Bobo family , and they deserve that . ''
